fixes#1119 "add test for the integrity of failover cluster
groups". Compilers require all failover group objects to be
configured with interfaces of member firewalls.
fixes#1120 "redundant commands generated for ssh
access". Compiler for PIX generated two "ssh address netmask
inside" commands for the same rule that permits ssh to the firewall.
"fwb_pix uses wrong interface compiling the second cluster
member". NAT compiler for PIX failed to find interface with
correct network zone if interface was a child of another
interface, e.g. vlan subinterface.
#1115: "fwb_pix crash compiling cluster NAT rule set with
interface in TSrc". A cluster interface was used in the TSrc rule
element of a NAT rule. Cluster interfaces of PIX cluster have no
ip addresses of their own (PIX HA pair uses ip addresses of the
master unit), this caused rule element to become empty after
interface object was supposed to be replaced with its ip address.
fixes#1115
* CompilerDriver_pix_run.cpp (CompilerDriver_pix::run): Added
support for failover configurations for PIX.
- Interfaces of member firewalls used for failover configuration
should be marked as "Dedicated failover" interfaces. They should
have normal IP addresses. These interfaces will be used to
generate "failover" commands in the PIX configuration.
- Cluster should have interface with the same name as failover
interfaces of the members, with protocol set to "PIX failover" and
members configured as usual. This interface has no ip address.
- Other interfaces of the cluster have the same name as
corresponding interfaces of the member firewalls, protocol "None"
and failover groups that define members as usual. These cluster
interfaces also have no ip address.
- Cluster state synchronization group uses protocol "PIX state
synchrnization" and its members should be configured as usual.
Use failover interfaces of the members as members of the state
sync group.
* Interface.cpp: Added attribute "dedicated_failover" to the
Interface object. Interfaces with this attribute are treated like
other "unprotected" interfaces, that is they are not used to
attach ACLs to and not used in rules. Dedicated failover
interfaces have special meaning in PIX configurations and are used
to describe interfaces used for LAN failover.
